2:17pm: Los Angeles has announced that it designated lefty Chris Reed for assignment to create 40-man space for Guilmet.
Reed, 25, came into the year rated the organization’s 10th-best prospect, per Baseball America, which said he could develop into a back-end starter or late-inning relief option. The 2011 first-rounder has had some uneven results in recent seasons, and was shifted to a pen role this year. Thus far in 2015, Reed owns a 5.97 ERA over 34 2/3 frames in the upper minors, with more walks (5.7 BB/9) than strikeouts (5.5 K/9).
12:27pm: The Dodgers have claimed righty Preston Guilmet off waivers from the Rays, Ken Rosenthal of FOX Sports reports on Twitter. His roster spot had been needed in Tampa Bay for the activation of John Jaso.
Los Angeles has made a notable habit of bringing in a steady stream of relief arms, and Guilmet now joins the flow. The 27-year-old only tossed 5 1/3 big league innings this season, but has spent at least some time in the majors over each of the last three years. While he hasn’t found much success in just 21 innings at the game’s highest level, he does own a promising 2.47 ERA, with 9.8 K/9 against 2.1 BB/9, in his Triple-A career.
